W10160407 Whirlpool Refrigerator Compressor is a sealed motor-compressor assemblyâ used in household refrigeration units. It is a compact, electrically driven âcompressorâ that serves as⤠the mechanical⢠heart of the vapor-compression refrigeration loop; the unit contains the compressor motor and pump in a hermetically sealed housingâ and typically includes external electrical terminals for the start relay and overload protector. As a⣠field-replaceable part number used on select Whirlpool⣠appliance models,it â˘is⣠specified to match particular electrical,mounting and refrigerant-system requirements.
Within the appliance, the âcompressor’s role is to draw low-pressure refrigerant vapor from⤠the âevaporator, compress it toâ a higher pressure and temperature, âand discharge the hot vapor to theâ condenser â¤where heat is rejected. The compressor therefore directly interfaces with the evaporator, condenser,â expansion device (capillary tube or âŁthermostatic expansion valve), refrigerant piping and the appliance’s electrical control circuitry (thermostat or control board, start relayand overload protection). Proper lubrication, correct system pressuresand secure âŁmechanical âmounting are all essential to its operation; failures or mismatches âin â¤any of thes interacting systems can affect cooling performance, noise,⤠reliability and electrical load.
this articleâ will describe the compressor’s functional characteristics and typical specifications, explain how to âverify compatibility with different Whirlpool models, summarize common failure symptoms (such as no cooling, continuous running, short-cycling, excessive noise or abnormal current⣠draw)and outline systematic troubleshooting checks a technician or informed appliance owner can â˘use to isolate compressor-related issues versus external causes. It will also cover practical replacement considerations-matching part numbers and system refrigerant/oil ârequirements, sealedâsystem work implicationsand safety/regulatory reasons to use certified service for refrigerant recovery and system evacuation-so readers can assess repair options and risks without relying on marketing claims or unverified procedures.

Function and Role of the Refrigerator Compressor in the Appliance Refrigeration Cycle
The âcompressor is the mechanical heart of the refrigeration âcircuit: â¤it draws⢠lowâpressure refrigerant vapor from the evaporator, compressesâ it to a higher pressure and temperatureand discharges that vapor into the condenser âŁso heat can be ârejected to ambient.â The W10160407 Whirlpool Refrigerator Compressor serves this âsame vaporâpump function and contains the electric motor, compression element (reciprocating or rotary), internal check valves and the start/overload devices.In normal operation the â˘compressor provides the mass flow that sets evaporator and condenser pressures; its on/off cycling isâ controlled by the thermostat and protective devicesand any mismatch in displacement, âŁrefrigerant⤠compatibility, oil type orâ electrical rating will change system pressures, efficiencyand reliability.
Practical technician âŁchecks focusâ on behavior ârather than cosmetic appearance: a healthyâ compressor will draw rated current, produce rising discharge temperature relative to suctionand create a meaningful pressureâ differential while the refrigeration loop is sealed and⣠charged with the correctâ refrigerant. â¤Common fault patterns⣠include failure to start (frequently enough caused by a bad⣠start relay or open windings), short cycling (thermostat or lowâcharge), unusually high discharge pressure (airflow obstruction, dirty condenseror overcharge) and loss âof suction pressure (leak or restriction). Replacement of the W10160407â or âany compressor requires matching electrical and refrigerant specifications, replacing the âfilterâdrier,â evacuating the system to proper vacuumand ensuring correct oil charge and brazed joint procedures to avoid contamination and premature failure.
- Primary roles: compress vapor, â¤maintain refrigerant mass flow, establish system pressure differential.
- Behavioral checks: current draw,â suction/discharge pressure behavior, temperatureâ riseâ across the compressor.
- Compatibility â¤items: refrigerant âtype, oil type/volume, electrical⢠voltage/frequency, mounting and service fittings.
- Common symptoms of failure: no start/humming, high current, low cooling,⣠or erratic cycling.

How the W10160407 Whirlpool Refrigerator Compressor Works Inside the Appliance
The W10160407 whirlpool Refrigerator Compressor is aâ hermetically sealed, singleâphase compressor assembly â˘that⢠contains the motor, pumpand internal valves within one steel shell.Internally â˘it uses a â¤start andâ run winding to drive a piston or rotary mechanism that raises refrigerant vapor⣠from evaporator suction pressure to condenser discharge pressure; this pressure differential is what circulates refrigerant âthrough the evaporator and condenser and enables heat transfer. in practical replacement â˘and compatibility terms,⢠the W10160407 is specified to match the original equipment’s electrical terminals, mounting patternand refrigerantâ circuit connections, but installers should always confirm nameplate voltage, terminal labeling (Common/Start/Run)and refrigerant compatibility before fitting it into a different⢠cabinet or model⤠series.
- Key operating behaviors: start-up âinrush current followed by steady ârunning âcurrent, heat on the compressor body⣠during operationand a â¤thermal âoverload that opens on excessive âtemperature âor current.
- Common diagnostic symptoms:⢠repeated clicking (failed start relay), continuous humming âŁwithout compressor â¤spin (seized or locked rotor), high running currentor inadequate cooling with warm evaporator temperatures.
- Service considerations: verify electrical continuity of windings, test the start relay and overloadand inspect for oil leaks or damaged vibration mounts before declaring compressor failure.
| Item | Description |
|---|---|
| electrical rating âŁ(typical) | 115-120 VAC singleâphase for most household whirlpool units-confirm nameplate on the compressor for exact rating |
| Terminals | Common, Start, Run; âproper relay/capacitor matching is required for reliable start-up |
| Mounting and service | Rubberâisolated base or bracketed mount;â replacement requires matching mounting points âand correct refrigerant handling by âcertified⤠technicians |
In-system behavior depends on the matched evaporator, condenserand thermostat controls: a properly functioning â¤compressor will cycle on demand, maintain designed suction and discharge pressuresand remain quiet aside from normal mechanical vibration. For practical troubleshooting, use aâ clamp meter to observe inrush versus runningâ current, listen for the distinct mechanical noises that indicate internal wearand check line âŁtemperatures at the suction⣠and discharge to assessâ compression efficiency.Because refrigerant charge, oil conditionand system restrictions (blocked capillary or TXV issues) can mimic⢠compressor⤠faults, definitive replacement⢠decisions should combine electrical, thermaland pressure measurements rather than relying on noise alone.
Common â¤Failure Symptoms and Diagnostic Indicators⤠of Compressor Malfunction
The W10160407 Whirlpool Refrigerator Compressor performs the core functionâ of compressing refrigerant to establish the pressure and temperature differentials required for â˘heat transfer in the sealed refrigeration circuit. In operation the compressor will draw a high inrushâ current âŁduring âstartup and then settle to a lower running âcurrent;â replacements such as the W10160407 must match electrical characteristics, mountingand oil/refrigerant compatibility to avoid mismatched load or lubrication issues.⤠Mechanical faults in this compressor often produce predictable âbehaviors: a unit that clicks repeatedly and never stays on â˘usuallyâ indicates a starting problem (relay or winding), a continuously humming but non-running compressor mayâ have seized internal componentsand an intermittently warm cabinet with poor evaporator frost patterns frequently âpoints to reduced compression⣠or refrigerant circuit problems rather than accessory faults alone.
- No start with repeated âclicking or tripping breakers.
- Hummingâ or â¤high-pitched vibration with little or no cooling.
- Excessive running time or short cyclingâ between on-off states.
- Elevated running current or unusually low current compared to âthe nameplate.
- Abnormal frost patterns â¤on the⢠evaporator or oil/refrigerant â˘odor near service ports.
Diagnostic evaluation combines electrical, thermal,â and pressure checks. Begin by verifying supply voltage and then measure running âŁand start currents with a clamp meter; compare âmeasured running âcurrent to the compressor nameplate and to manufacturer service literature. Use an ohmmeter âŁto check terminal resistances âand insulation to ground-open windings give infinite resistance while shorted or grounded windings reduce insulation resistance.Test the start relay and any start capacitor with a bench test or swap with a known-good unit; if the compressor draws rated current but fails to build discharge pressure on manifold gauges, expect an internal mechanical failure or a refrigerant charge problem. Practical examples: a compressor with normal electrical readings but zero pressure rise on the discharge indicates internal valve or piston failure, whereas high amp draw with elevated case temperatures âsuggests mechanical⣠seizure or lubrication breakdown.

Replacement Considerations and Installation Procedures for the W10160407 âCompressor
The W10160407⢠Whirlpool Refrigerator â¤Compressor is a hermetic ârefrigeration compressor that compresses vapor from the evaporator and provides the pressure differential required for the refrigerant loopâ to transfer heat. Technically, replacement requires matching the compressorS electrical rating, mounting footprint, suction and discharge port sizes, âand internal oil compatibility âwith the system⣠refrigerant; mismatches can cause âhigh starting currents, improper oil return or accelerated wear. â¤In practice, technicians âŁshould confirmâ the service history and⤠operating symptoms – such as, a compressor that ran hot and tripped the overload may have driven debris through the system or contaminated the oil, so installing a new W10160407â Whirlpool Refrigerator â˘Compressor⣠without flushing the refrigeration circuit and replacing the filter-drier can result â˘in premature failure.
Installation procedures focus on preserving system integrity and restoring correct charge and oil balance: first safely recover ârefrigerant to an approved recovery cylinder, then remove electrical connections and service tubing using proper brazing technique while purging with dry nitrogen to limit oxidation. After installing the compressor and a new filter-drier, evacuate the system to a deep vacuum, verify leak-tightnessand charge the system to âŁthe original manufacturer specification byâ weight while monitoring running amperage âand pressures to âensure normal operation. Practical steps and checks include:
- Recover refrigerant and disconnect mains power.
- Remove old⣠compressor and filter-drier; inspect lines forâ debris and damage.
- install new compressor and replace the filter-drier; braze with nitrogen purge to avoid oil carbonization.
- Evacuate the system to 500 microns and hold to confirm no leaks and remove moisture.
- charge âwith specified refrigerant and oil if needed, then monitor ârunning⣠current âŁand system pressures under load.
| Item | Description |
|---|---|
| Mounting | match âŁfoot pattern and vibration isolators to avoid mechanical stress on lines and chassis. |
| Electrical | Confirm line voltage, capacitor/relay requirementsand expected locked-rotor/run âcurrents before commissioning. |

Q&A
what is⣠part âW10160407⤠and which Whirlpool refrigerators use it?
W10160407 is a Whirlpool part number used to identify a replacement sealed-system compressor assembly offered for certain Whirlpool, Maytag and KitchenAid refrigerators. Itâ is not universal – compatibility depends on âŁthe refrigerator model and the compressor modelâ code printed on the compressor nameplate. Always verify the appliance model number⢠and the compressor model number (on the compressor label) against the part cross-reference beforeâ buying or âinstalling.
My refrigerator is â˘warm⢠and the compressor isn’t running. could W10160407 be the problem?
A failed compressor can cause the âŁrefrigerator to stop cooling,but other components commonly cause theâ same symptom: âa failed start relay/overload,a bad thermistor/control board,a blown fuse,or an open power supply. Before replacing the compressor, check that the compressor gets proper⤠voltage, listen for âclicking (relay trying to â¤start), test the start relay and overload deviceand perform simple electrical tests on the compressor windings (see ânext question). If the compressor windings are intact and it still won’t start, the âstart device or control circuit is more likely the cause.
How do I test a compressor like W10160407 safely?
First, disconnect mains power. Remove the compressor electrical⢠access cover and disconnect the wires. Use a âŁmultimeter to measure âresistance between the three terminals: Common, Start and âŁrun.You âshould⢠see finite resistance between the terminals (not an⣠open circuit) and a common pattern âwhere⤠two readings add to the third (Run + Start â Common, relative values vary). Also⣠check for continuity⣠betweenâ any terminal and âŁthe compressor case – there should be none (infinite resistance). If you see an open winding or continuity to ground, âŁthe compressor is electrically failed. For⢠a running test, measure current draw at the⣠compressor with a clamp meter; âexcessively high current, very low⤠current (not running) or rapid cycling âindicates a problem. If you’re not comfortable performing these tests, hire a qualified â˘technician.
can I replace W10160407 myself and what is involved?
Replacing a sealed-systemâ compressor is complex and regulated. It requires recovering refrigerant, cutting and brazing refrigerant lines, replacingâ dryer/accumulator, vacuuming the system to deep vacuum, leak testingand recharging the exact⢠refrigerant charge and oil type.These tasks require EPA certification (or local equivalent), specialized tools,⢠and brazing â¤skill.Electrical and⣠mounting work is straightforward, but the sealed-system service should be âŁdone by a certified refrigerationâ technician. Ifâ the unit is under warranty, contact Whirlpool or a factory-authorized âservicer first.
What are common symptoms of a failing W10160407 compressor besides no cooling?
Common symptoms include: loud or abnormal noises (grinding, knocking), frequentâ start/stop cycling, running â˘hot to the touch, âtripping household breakers, â˘or the âcompressor humming but not starting (sometimes accompanied by clicking of the relay). Some intermittent failures show⤠up as occasional loss of cooling or long run⤠times. Though, similar symptoms can be caused by start⣠relays, âŁcapacitors (on some designs)or control electronics, so confirm the diagnosis before replacing the compressor.
How longâ should a refrigerator compressor like W10160407 last?
with proper use and maintenance, modern refrigerator compressors often last 8-15 years or longer. lifespan âdepends on usage patterns, ambient â¤temperature, cleanliness of condenserâ coils, â˘and whether the sealed system remains leak-free. Frequent power interruptions, restricted airflowor prolonged high ambient temperatures can shorten compressor life.If⤠your fridge is older and theâ compressor fails,weigh the cost of compressor replacement (plusâ sealed-system work)â against replacement of the entire appliance.
Isâ there a way to reduce the chance of damaging the compressor during installation?
Yes – follow manufacturer guidelines: ensure the correct compressor orientation during transport and initial installation, allow oil to settle if the compressor was laid on its side per instructions, use proper vibration-isolation mounts, torque mounting bolts correctly, replace the filter/drier, evacuate and leak-test the system before chargingand use the proper refrigerant and oil. Also confirm correct electrical connectionsâ and proper⢠line voltage. Improper handling, â˘moistureor contamination of the sealed system can damage a new compressor quickly.
How much does replacing a compressor like W10160407 typically costand is it âŁworth it?
Costs vary widely by region and whether parts like the evaporator, condenseror accumulator also need replacement. Expect â˘several hundred to over a thousand dollars for parts and certified labor (recover/recycle refrigerant, replace compressor and drier, braze âlines, evacuate, recharge). For older âor lower-cost ârefrigerators, replacement cost is often close to or⢠exceeds the price of a new appliance. For newer high-end models,â sealed-system repair can âbe cost-effective. Get an itemized quote and consider appliance age, warranty statusand overall âcondition before deciding.
In Summary
The W10160407 Whirlpool refrigerator compressor serves as the central â˘component of the appliance’s cooling system, compressing refrigerant and enabling heat exchange to maintain stableâ internal temperatures. Its reliable operation is critical to food preservation, energy efficiency and overall appliance performance; a failing compressor commonly manifestsâ as inadequate cooling, excessive cycling or unusual noise and, if left unaddressed, âcan lead to further⢠damage or spoilage.
